Overview about Liquid and string filter
Liquid has been launched since 2006, until now it is used on a lot of digital platforms including Shopify and Jekyll. It includes many logical and comparison operators. Basic operators are often used in Liquid code so that you can change or separate items in order to show what you want.
Liquid is classified into three types: objects, tags and filters. Objects show the content on a page. Tags create logic and control flow for templates while filters change the output of variables.
Liquid offers five types: string, number, boolean, nil and array. Number includes floats and integers. Boolean response to true or false value. Nil is a special empty value that is returned when Liquid code has no results. Today, string filter is our focus.
String filters are used to manipulate outputs and variables of string types.
Information about url and url parameters
A uniform resource locator (URL) is the address of a resource on the Internet. A URL indicates the location of a resource as well as the protocol used to access it. It contains information such as: the protocol used to access a resource, the location of the server, the location of the resource in the directory structure, a fragment identifier.
URL_param_escape filter replaces all characters not allowed in URLs with URL-encoded equivalents, including the ampersand character. If you want to leave the ampersand character unchanged, you should use the URL_escape filter.
